To be fair, while paradox games like Stellaris or the crusader kings games you mentioned, certainly have a lot of replayability (I don’t really care much for CK myself but have over 1000 hours on both Stellaris and EU4), they’re not great examples for where cheaper games by smaller companies offer more than expensive ones from bigger ones. Partly because paradox is fairly sizable and well known these days, but mostly because those games are quite expensive, just split into numerous expansions that come out over time. One can opt out of getting them, sure, but they’re where a lot of the different options that bring the replayability come from.

Satisfactory is a weird game where coal and oil are renewable, but trees, as far as I’m aware, are not.
